STOP MECHANISM FOR MACHINERY.

Application filed December 30, 1909.

To all whom it may concern Be it known that I, DANIEL M. Goornn, of Rochester, in the county of Monroe and State of New York, have invented certain new and useful Improvements in Stop Mechanisms for Machinery; and I do hereby declare the following to be a full, clear, and exact description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the reference-numerals marked thereon.

The present invention relates to stop mechanisms for machinery and it has for an object to provide a construction which will utilize the driving or motor power for its operation so as to positively insure a stopping of the machine.

To these and other ends the invention consists in certain improvements and combinations of parts all as will be hereinafter more fully described, the novel features being pointed out in the claims at the end of the specification.

In the drawings: Figure 1 is a side view of a mangle with the present improvements attached thereto; Fig. 2 is a top view of the stop mechanism, with parts broken away and other parts in section; Fig. is a vertical sectional view in the direction of the axis of the shaft, and Fig. 1 is a vertical section on the line a--a of Fig. 3.

In the embodiment of the invention herein illustrated there is employed a shifter adapted to break connection between driving and driven parts. In this instance, the driving parts comprise a pulley 2, keyed at 3 to a sleeve 4: turning on the shaft 5 which is journaled on frame 14, while the driven parts comprise a sleeve 6, keyed to the shaft 5 at 7 and carrying a pinion 8 connected to the operating parts of the machine to be stopped, such as a mangle A. Connection between such parts is preferably established by an axially movable clutch member 9, keyed at 10 to the sleeve 4 for axial movement thereon and having clutch faces 11 adapted to coiiperate with clutch faces 12 on the sleeve 6. The shifter 1 may be in the form of a lever pivotally supported between its ends at 20 and having one end yoked at 21 and provided with inwardly extending projections 22 operating in an annular groove 23 in clutch member 9.

The mechanism for moving the shifter preferably comprises a swing member 13 or Specification Of Letters Patent.

segment adapted to turn or oscillate 011 the frame 14 about an axis 15 parallel with and below the shaft 5, a stop 16 on the frame eooperating with the abutment 17 on the swinging member to limit the movement of the latter in one direction. The swinging member in this instance has formed on one face a cam surface 18 preferably curved about the axis 15 as a center and adapted to cooperate with a roller 19 on the shifter 1 to move the latter about its axis 20, thus causing the member 9 to be moved out of en gagement with sleeve (3. The lateral strain imposed upon the cam member 13 by the shifter may be taken up by a brace 25) bolted at 30 to the frame 1 1 and having a roller 30 thereon cooperating with that face of the member 13 opposite the one engaged by the shifter.

The movement of the swinging or oscillatory member 13 is preferably effected by a dog 24 pivoted at 25 to the swinging member and having a shoulder 26 thereon adapted to be moved upwardly into the path of radially extending projections 28 of the rotary sleeve 1, whereby during a part of a revolution of said sleeve the dog will be moved (in a direction toward the right in Fig. at) to rock the member 13. The upward movement of the dog is limited by an extension 29, beyond the shoulder 26, which engages the periphery of the sleeve 1.

lllovement of the dog 2 1 into the path of the projections 28 may be effected in any suitable manner. In this instance a lever 31 pivoted at 39 to the frame let has a surface 33 thereon cooperating with a roller 34-. on the dog in a manner to support said dog substantially in a horizontal position, as shown in Fig. t. A stop or shoulder 35 on the lever cooperates with a stop or shoulder 36 on the frame 14tto limit the downward movement of the lever. The upward move ment of the latter is in this instance effected by a pull bar 37 extending upwardly to an arm 38 on the shaft of a finger board 39 which is arranged at the intake of a mangle A, the latter having its drive wheel l0 geared to the pinion 8 of the stop mechanism.

In operation, should the hand of the operative of the mangle engage the finger board 39, the pull bar 37 will swing the lever 31 to carry dog 24: into the path of the projections 28. Upon engagement of one of one side thereof codperating with tween said part and the swingin on weights or springs but utilizes the motive power of the machine to which it is applied as means for actuating it.

I claim as my invention.
